Switchres: modeline generator engine
Sledge:
So i'm just trying to understand some of this resolution/modeline/Hz/etc stuff
I have a question though..
Galaga natively runs at: 288 x 224 (V) 60.606061 Hz
But Switchres chooses: 2560 x 288p 51.774 Hz 16.050 KHz
But if i press F11 during gameplay it says it's running at 100%
How does this work if it's running at 51.774Hz instead of 60 Hz ? Is it running at it's correct speed or not?

Obviously the refresh is not correct (it can't be on a standard arcade monitor). But the speed is, because we detach the emulation from the refresh. This is achieved by triple buffering (multithreading must be enabled for this). GM enables triple buffering automatically when it judges the target refresh is going to be too off, being the default threshold 2.0 Hz. You can modify this value through the -syncrefresh_tolerance option in mame.ini.

I fixed some bad bugs (related to memory allocation).
You can find the updated version here.

Hello,
I am new to this forum and I hope to write in the right section.
I have some problem with Groovymame and Switchres.
I state that I disabled in MAME.INI interlaced resolutions because they do not love them.
With the desktop resolution to 640x480, and Groovymame Swithchres working properly.
If instead you imposed the desktop resolution to 640x240 and Groovymame Swithchres only work for a few games.
Rampage games by type, Paperboy, 19xx, Twincobra, maintains it in exchange for a resolution.
For other types Metalslug, Rolling Thunder, Pacman (Midway) work perfectly.
Some idea?
Use CRTEmudriver 6.5, ATI x300, Groovymame 0148u5.014b and WindowsXP.
Thank you.

Hi
Coming from here. Groovymame creates a good modeline for sega genesis but standalone switchres doesn't. I gues groovyarcade's switchres comes from this 4 year old git repository, so it may be the problem.

I've found a newer repository here.
https://github.com/antonioginer/switchres
So cloned it and tried to compile for testing, but I get dependency errors... (SDL_syswm.h). That's strange because I've compiled MAME with groovymame patch in this machine with no problem. Any help for compiling? I'm using debian, but can try from arch.
